1. Acyclovir is the drug of choice for:

A. HIV
B. HSV 1 and 2 and VZV
C. CMV
D. influenza A viruses

Correct answer: C

Rationale: Acyclovir (Zovirax) is specifically used to treat infections caused by herpes simplex virus types 1 and 2 (HSV-1 and HSV-2) and varicella-zoster virus (VZV). These include conditions like cold sores, genital herpes, and shingles. Acyclovir works by inhibiting viral DNA replication, leading to the formation of shorter, ineffective DNA chains. It is important to note that acyclovir is not effective against other viruses like HIV, cytomegalovirus (CMV), or influenza A viruses. Therefore, the correct answer is HSV 1 and 2 and VZV.

2. After experiencing a left frontal lobe CVA, a fifty-five-year-old man is being monitored by a nurse. The patient's family is not present in the room. What should the nurse observe most closely for?

A. Changes in emotion and behavior
B. Monitor loss of hearing
C. Observe appetite and vision deficits
D. Changes in facial muscle control

Correct answer: A

Rationale: The correct answer is to watch for changes in emotion and behavior. The frontal lobe, particularly the left side, is responsible for regulating behavior and emotions. Therefore, following a left frontal lobe CVA, monitoring for alterations in emotion and behavior is crucial. Choices B, C, and D are incorrect because loss of hearing, appetite and vision deficits, and changes in facial muscle control are not directly associated with a left frontal lobe CVA.

3. In alcoholics with anemia:

A. Pernicious anemia is more common than folic acid deficiency.
B. Iron deficiency and folic acid deficiency can coexist.
C. The alcohol interferes with iron absorption.
D. Oral vitamin replacement is contraindicated.

Correct answer: B

Rationale: In alcoholics with anemia, iron deficiency and folic acid deficiency can coexist due to poor dietary intake and malabsorption issues associated with chronic alcohol consumption. Pernicious anemia, primarily related to vitamin B12 deficiency, is not commonly seen in alcoholics. While alcohol can interfere with iron absorption, it is not the sole factor contributing to anemia in alcoholics. Oral vitamin replacement is not contraindicated in alcoholics with anemia; however, it may be less effective due to absorption issues related to alcohol consumption.

4. When discussing possible complications of pregnancy with a client, the nurse should explain that all of the following are symptoms of urinary tract infection (UTI). Which of the following is least indicative of UTI during pregnancy?

A. low back pain
B. urinary frequency
C. GI distress
D. malaise

Correct answer: B

Rationale: Urinary frequency is least indicative of UTI during pregnancy. It is a common minor discomfort of pregnancy caused by pressure of the growing uterus on the bladder. As the uterus rises in the second trimester, there are usually no problems. Frequency may return in the third trimester when the uterus drops into the pelvic cavity. UTI symptoms include low back pain, suprapubic discomfort, and malaise, and are confirmed by laboratory findings. Low back pain, GI distress, and malaise are more closely associated with UTI during pregnancy compared to urinary frequency.

5. A client had a C5 spinal cord contusion that resulted in quadriplegia. Two days after the injury occurred, the nurse sees his mother crying in the waiting room. The mother asks the nurse whether her son will ever play football again. Which of the following is the best initial response?

A. "Given time and motivation, your son may regain some function, but I will seek more information from the physician."?
B. Maintain a calm demeanor and speech pattern while addressing the mother's concerns.
C. "I'm not sure, but I'll call the physician to discuss this with you promptly."?
D. "It's not beneficial for your son if you get upset."?

Correct answer: C

Rationale: The best initial response in this situation is to acknowledge the mother's concern, express uncertainty, and offer to obtain more information from the physician. By saying, "I'm not sure, but I'll call the physician to discuss this with you promptly,"? the nurse demonstrates empathy, honesty, and a commitment to providing accurate information. Offering vague reassurance (Choice A) may raise false hopes as outcomes for spinal cord injuries are unpredictable. While maintaining a calm demeanor (Choice B) is important, it does not directly address the mother's immediate need for information. Discouraging the mother from feeling upset (Choice D) is dismissive of her emotions and does not address her question, which is seeking information about her son's prognosis.
